4 2 Claims.

This case relates -to the striping means of a .machine. for operating onta web to' produce printed recordcards therefrom, and is a" division ofmyapplicationSerial No. 122,360, filed January 26, .1937 and granted as Patent No. 2,181,935,

dated December-.5, 1939.,

The .machinepperatesron a blank continuous strip of material; -i.-e., the web, to print record forms thereon which are cut apart-toiorm card 10 lengths each bearing one printed form. The

- particular record produced is known as a tabulating card which in subsequent use is punched to control automatic bookkeeping or accounting machines.

To-provide rough classification means for the cards, they are often striped along one edge. The simplestand most economical method of producing "the stripe on each card is to apply thestriping material to one longitudinal edge of i the web while the web=is feedingthrough the card forming machine, which forms the cards from theweb. Thevstriping material, when applied to the edges of thewebor cards, tends to swell and soften suchedge. One-result is that if one edge of the cardis :provided 'witha continuous stripe along its entire length, there is a tendency for the card toccurl orwarp.

Another result of providing a continuous stripealong the entire length of .an edge of the card is 'thatduring the handling of this card in an accounting machine or the like, the engagement of the softened edgewith the handling means, such as the ordinary card pickenhas a tendency to bend, crimp and damage the card. 35 In order to avoid the above undesirable results, an objectotthishinvention is to provide means for producingan intermittent stripe along an edge of the weblfromuwhich the cards are being formed. r 4 Further, theobject is to provide means for intermittentlyv striping. a continuously fed web so that each card produced therefrom hasa stripe along an intermediate portion of an edge, leaving the remaining portions of the edge, at either side of the: stripe, unstriped.

A more general object is to provide novel means for producinga stripe on: cards, such as tabulating cards.

Another general object is to provide novel striping means forany web.

Further objects of the instant invention reside if any novel feature of construction or operation or novel'combination of parts present in the embodiment. of the invention described and shown in .the accompanying' drawing, whether within or without the scope of the appended claims and irrespective of other specific statements as to the scope. of the invention contained herein.

In the drawing:

Fig. 2 is a section along lines 2-2 of Fig, 1;

Fig. 3 shows the card produced by the machine.

The striping means comprises a well 350 for the striping ink. The supply of striping ink, which may be red, green or some other suitable color, is contained in a bottle 35| carried on an incline by a spring clamp 352, which is suspended II by a strap 353 from the frame. The neck of the bottle is connected by a rubber tube 354- to a ferrule 355 fitted into an orifice at the bottom of ink well 350. The ink flows by gravity from bottle 35! through tube 354 and ferrule 355 into the well 350 where it occupies a lower level than in the bottle due to the well being open at the top so that the ink therein is subjected to atmospheric pressure, whereas the ink in the bottle is below a vacuum until it reaches a level below the top of the opening in ferrule 355.

Journaled in the well 350 is a rotatable rubber roller 356, the lower portion of which dips into the ink to keep the surface of the roll wet with ink. Near its upper end, roll 356 is in peripheral engagement with a rotatable rubber-covered striping roll 351 which takes the ink from roll 356. The web C is fed continuously from a supply roll (not shown) to the web forming means (not shown), and during its continuous travel to the latter passes, in the direction indicated by the arrowin Fig. 1, between a guide roller 31a andthe striping roll 351. The means for feeding the web C and the means for producing from this web the individual cards T (Fig. 3) are explained in my aforementioned application, Serial No. 122,360, of which this is a division, and need not bedescribed herein. It is understood that the striping means herein disclosed is applicable to any continuously fed web.- As the web is fed between roll 31a and a striping I roll 351, the "friction between the web and the two rollers causes their rotation. The peripheral engagement of the striping roll 351 with the wiping roll 356 in turn causes rotation of the latter roll. Rotation of roll 356 causes rotation of roll 358. During engagement of the roll 351 with the web and its rotation thereby, the latter .roll applies the ink to the web to stripe it along .the left edge (as viewed in Fig. 2).

To wipe off the excess ink from the periphery of ink roll 356, the latter is constantly engaged by a roller 358 carried by a pivotally suspended yoke 359 which is urged by a wire spring 360 toward the roll 356. Thus, roller 351 is yieldingly maintained against the periphery of roll 356. Also carried by arm 359 are wiping wires 362 constantly engaging the sides of the roll 356 to wipe off the ink therefrom. The wiping elements 358 and 362 engage portions of the ink roll 356 as these portions travel toward striping roll 351 so that the excess of ink is removed before reaching the striping r011.

Striping roll 351 is rotatably mounted on a rod 1' 363 carried by the forward end of a bail 364 pivoted at the rear to the lower end of a bell crank 365. Between the bail 364 and crank 365 is a wire spring 366 for lightly holding the striping roll 351 against the periphery of ink roll 356. A coil spring 361 connected to bell crank 365 urges the latter clockwise (Fig. 1) to maintain striping Lroll 351 in a forward position, firmly against the web C feeding over roll 31a.

The upper arm of bell crank 365 abuts a rod 366 extending horizontallyfrom the lower end of an arm 369 fixed to a shaft 310. Shaft 310 has an upwardly extending arm 31l, the upper end of which is bent laterally to engage the periphery of a cam 312 carried by the hub of a gear 313 in the driving train of the machine. During each revolution of gear 313, cam 312 acts on the upper end of arm 31l to oscillate shaft 310 and its arm 369. During the clockwise stroke of arm 369, the rod 368 thereof acts on the upper arm of bell crank 365 to rock the latter counterclockwise (Fig. 1), causing bail 364 to move rearwardly, or to the right. As bail 364 .moves to the rear, it causes striping roll 351 to roll rearwardly on the periphery of ink roll 356, thereby departing completely from the web. It .may be noted that roll 356 acts as a guide for the movement of striping r'oll 351 away from and towards the web, and so guidesthe striping roll that it leaves or engages the web abruptly in a direction substantially at right angles to the web. As the striping roll withdraws from the web, its rotation by frictional engagement withthe latter ceases, and since the striping roll has ceased rotating, ink roll 356 also stops rotating. Thus, when in retracted position, the striping roll has no striping fluid fed thereto by roll 356, and since the striping roll has stopped rotating it does not tend to throw off any of the striping fluid through the opening in the well 350.

The web continues to feed uninterruptedly during the interval in which striping roll 351 is withdrawn therefrom. During the counterclockwise stroke of shaft 310, spring 361 returns bell crank 365 in a clockwise direction, causing bail 364 to move to the left and restore striping roll 351 to engagement with the web C. While engaged with web C, striping roll 351 paints a stripe along the edge of the web. Due to the intermittent engagement with and withdrawal from the web C of the striping roll 351, a regularly broken or in- .terrupted stripe S (see Fig. 3) is painted by the striping means along one longitudinal edge of the web. Gear 313 makes one revolution for each individual card length produced from the web C, and the cam 312 of the gear is so proportioned as to cause the successive engagement and disengagement of the striping means to be of substantially equal duration, so that the length of the stripe S and the length of the unpainted portion between the stripes are substantially the same. The timing of the operation of the striping roll 351 is such that when the web is subsequently ut into cards 'I the stripe S is located intermedia ly between the side edges of the card and along the bottom edge thereof, as indicated in Fig. 3.

By thus providing an intermediate stripe along the bottom edge of the card, unstriped portions are left adjacent each side edge of the card. These unstriped portions of the card are usually the ones which are engaged by the feed means during the subsequent handling of the card in accounting machines or the like. Since the unstriped edge portions of the card are in the original condition, they are sufficiently resistant to bending, crimping. or distortion by the feeding engagement. At the same time, the cards are striped to provide rough classification means.

While there has been shown and described and pointedout the fundamental novel features of the invention as applied to a single modification. it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the following claims.

What is claimed is: v

1. In a machine through which a web is continuously feeding; striping means for the web comprising a striping roll engageable with the web and rotated thereby during feed of the web for striping the latter in its direction of feed, means for supplying striping fluid to-the periphery of the roll, a carrier for the striping roll mounted for reciprocation, and means for automatically reciprocating the carrier to periodically retract the striping roll from engagement with the web so as to interrupt the striping action of the roll and provide the web with an intermittent stripe, the disengagement of the roll from the web also interrupting the rotation of the roll to prevent the roll from throwing off striping material onto the web while the roll is disengaged from the web.

2. In a machine through which a web of sheet material is feeding; striping means for theweb comprising a striping roll engageable with the web and rotated by such engagement during feed of the web to stripe the latter in the direction of feed, a roller in peripheral engagement with the striping roll to be rotated thereby during rotation of the latter roll so as to feed striping material to the periphery of the striping roll during the engagement of the latter with the web, and means for automatically periodically retracting the striping roll from engagement with theweb so as to periodically interrupt the striping action and the rotation of the striping roll and of said roller, whereby feed of the striping material to the striping roll ceases and whereby tendency of the striping material to .be thrown off by the striping roll is obviated due to cessation of rotation of the latter roll.
